Win 7/10. MS 2.2.1, 51b8386 (also present in latest 2.3 nightly)

  1. Open MS and load the attached score.
  2. Quickly open the synthesizer and press "Load from Score."

You will get a hang/crash if this is done quickly enough. At a guess, this happens because the soundfont is still decompressing. If you have a "super-fast" system you may have difficulty reproducing the issue.

Bumping this. You have to wait for the soundfont to load, and notes to make sound, before loading new soundfonts from the score data. Very frustrating indeed when you might want to make a quick update to a score. Also, this is reproducible 100% of the time for someone with a slow hard drive such as I. It was made far more common after 3.0 probably due to the size of General Musescore.
Anyway, would be nice to have a fix. Worth noting is that loading soundfonts the standard way works perfectly fine (perhaps a bit slower).

Nope, nope, false alarm. It just happened again. It seems like it's simply harder to crash instead of crash-proof, so to speak (as before it would crash 100% of the time).
